Create and manage virtual networks for Azure Database for PostgreSQL - Flexible Server using the Azure portal
APPLIES TO: Azure Database for PostgreSQL - Flexible Server
Azure Database for PostgreSQL - Flexible Server supports two types of mutually exclusive network connectivity methods to connect to your flexible server. The two options are:
- Public access (allowed IP addresses)
- Private access (VNet Integration)
In this article, we focus on creation of PostgreSQL server with Private access (VNet integration) using Azure portal. With Private access (VNet Integration), you can deploy your flexible server into your own Azure Virtual Network. Azure Virtual Networks provide private and secure network communication. With private access, connections to the PostgreSQL server are restricted to your virtual network. To learn more about it, refer to Private access (VNet Integration).
You can deploy your flexible server into a virtual network and subnet during server creation. After the flexible server is deployed, you cannot move it into another virtual network, subnet or to Public access (allowed IP addresses).
To create a flexible server in a virtual network, you need:
- The virtual network and subnet should be in the same region and subscription as your flexible server.
- The virtual network should not have any resource lock set at the VNET or subnet level, as locks may interfere with operations on the network and DNS. Make sure to remove any lock (Delete or Read only) from your VNET and all subnets before creating the server in a virtual network, and you can set it back after server creation.
To delegate a subnet to Microsoft.DBforPostgreSQL/flexibleServers. This delegation means that only Azure Database for PostgreSQL Flexible Servers can use that subnet. No other Azure resource types can be in the delegated subnet.
Microsoft.Storageto the service end point for the subnet delegated to Flexible servers. This is done by performing following steps:
- Go to your virtual network page.
- Select the VNET in which you're planning to deploy your flexible server.
- Choose the subnet that is delegated for flexible server.
- On the pull-out screen, under Service endpoint, choose
Microsoft.storagefrom the drop-down.
- Save the changes.
If you want to set up your own private DNS zone to use with the flexible server, see private DNS overview documentation for more details.
Create Azure Database for PostgreSQL - Flexible Server in an already existing virtual network
- Select Create a resource (+) in the upper-left corner of the portal.
- Select Databases > Azure Database for PostgreSQL. You can also enter PostgreSQL in the search box to find the service.
- Select Flexible server as the deployment option.
- Fill out the Basics form.
- Go to the Networking tab to configure how you want to connect to your server.
- In the Connectivity method, select Private access (VNet Integration). Go to Virtual Network and select the already existing virtual network and Subnet created as part of prerequisites.
- Under Private DNS Integration, by default, a new private DNS zone will be created using the server name. Optionally, you can choose the subscription and the Private DNS zone from the drop-down list.
- Select Review + create to review your flexible server configuration.
- Select Create to provision the server. Provisioning can take a few minutes.
After the flexible server is deployed to a virtual network and subnet, you can't move it to Public access (allowed IP addresses).
If you want to connect to the flexible server from a client that is provisioned in another VNET, you have to link the private DNS zone with the VNET. See this linking the virtual network documentation on how to do it.
